Same here, PS4 user on the Crystal server. Though I have had problems each and every day logging in for at least 8 months, not always just 5006. Ever since Shadowbringers launch...well very shortly after...and I got a newer PS4. If I wait 10 sec before selecting something during log in it will give me a 5006 and automatically disconnect/not connect to the PS Network. Requires a full reboot every single time. Also happens if I wait 5 min to start up XIV from the main menu.
